set the engine to PROPER tdc AND the cam to the normal TDC as per timing marks, then remove the normal vernier and fit the after market one, then you know the engine is at the general TDC, now turn the crank 360 degrees so you are on overlap and then set the crank to the correct timing point for timing it too and adjust the vernier to have the valve fully open, job done as far as im aware
